Abstract:
Described herein are various methods and manufacturing methods for making antimicrobial and strengthened, antimicrobial glass articles and substrates. The methods described herein generally include contacting the article with a KNO 3 -containing molten salt bath set at about 380C to about 460C for about 30 minutes to about 24 hours to form a compressive stress layer that extends inward from a surface of the glass substrate to a first depth; and contacting the article comprising the compressive stress layer with a AgNO 3 -containing molten salt bath set at about 300°C to about 400°C for about 5 minutes to about 18 hours to form an antimicrobial region that extends inward from the surface of the glass substrate to a second depth. The methods also include poisoning at least the AgNO 3 -containing molten salt bath and, in some cases, the KNO 3 -containing molten salt bath. Poisoning components include Na + and Li + ions.
Abstract:
Described herein are various antimicrobial glass articles that have improved strength and resistance to discoloration. The improved antimicrobial glass articles described herein generally include a glass substrate with a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth. In some embodiments, the compressive stress layer has a compressive stress at the surface of about 500 MPa or greater and the compressive stress decreases monotonically from the surface into the depth of the glass substrate. Methods of making and using the glass articles are also described and include forming a compressive stress layer and forming an antimicrobial silver-containing region by preferentially exchanging a plurality of silver cations in a silver-containing medium for a specific plurality of first cations ions in the glass substrate.
Abstract:
An armoured resistance (2) for heating the water of an electric storage water heater or the sump of a laundry machine or a dishwasher is provided. The metal surface in contact with the water to be heated thereof is covered with a glass enamel, on the surface whereof metals (Ag, Cu, Zn) having antibacterial properties are deposited according to known techniques. The deposited metal is preferably silver and, even more preferably, it is in the form of nanoparticles.
Abstract:
A coated article is disclosed. The coated article (200) comprises an antibacterial coating (1 ) on a glass susbtrate (3), the substrate (3) having a modified surface layer (2) which essentially reduces the ion exchange between silver in the antibacterial coating (1 ) and sodium in the glass susbtrate (3). Apparatus and method for forming such article are also disclosed.
Abstract:
A process for the production of a substrate having antimicrobial properties is described and a substrate. It comprises a step consisting of the deposition of a metal non-gelling layer comprising an inorganic antimicrobial agent; and a step consisting of the diffusion of the agent into said at least one exposed surface of the substrate by thermal treatment. Alternatively, the substrate may be first coated with an underlayer and the diffusion occurs in the underlayer. Substrates having antimicrobial properties are also described. In particular, a substrate exhibiting a bactericidal activity measured in accordance with standard JIS Z 2801 of higher than log 2. In particular tempered glass maintaining antibacterial properties after accelerated ageing tests are obtained.
